In other words, the subdivision doesn't end at the fence or the sidewalk. Accurately "ungluing" the area from the roadway means mapping the curb.

The pavement itself is publicly owned and accessible, as part of an 
easement. The landowner still has certain rights, but not the right to 
regulate public use of the roadway.

Still, mapping to the centerline in this case does meet the "what you 
see on the ground" rule of thumb: when a piece of private property 
fronting the road changes ownership, the public notice typically 
references the centerline (i.e., lane markings) or a particular spike 
embedded somewhere on the roadway.

This is admittedly a very technical distinction, but I think it shows 
that joining landuse areas to the centerline is perfectly valid in 
certain circumstances.
